3 Claims; (c1.14s--102) This invention relates to slicing machines; andmore particularly to the type wherein the material is manually movedalong the material rest or feedway during the slicing operation.

One of the main objects of this invention is to provide a simple andreadily operable slicing machine which is economically constructed sothat it can be placed on the market at a minimum of cost, and willtherefore find a ready sale. Another object is to provide a slicingmachine whichis so constructed that the customary reciprocating materialsupport will be entirely omitted therefrom, for the sake of economy. Afurther object is to arrange the various parts of .15 this machine sothat the gage plate can be utilized as a guard for protecting thenormally-exposed cutting portion of the knife, while the machine is atrest, and thereby cooperate with the customary knife guard and inconjunction therewith provide a complete guard for the knife. These andother objects are attained with this invention, as will appear from thefollowing description, taken in connection with the accompanyingdrawings, in which:

Fig. 1 is an end elevational view of a slicing machine embodying thepresent invention.

Fig. 2 is a front elevational view thereof. Fig. 3 is a plan viewthereof. Fig. 4 is an enlarged detail section, taken on 301line 4-4 ofFig. 1.

Fig. 5 is an enlarged detail section, taken on line 5-5 of Fig. 1, andshowing how the gage plate functions as a guard for the exposed cuttingportion of the knife.

comprises a base 10 provided with an upwardlyslanting standard 11 at theupper end of which the rotary slicing knife 12 is mounted, A bracket 13is also provided on the base whereon is mounted the motor 14 for drivingthe knife.

A material rest or table 15 is mounted on the base in aninclined-position with the horizontal, substantially as shown inthedrawings, and it is preferably provided with depending flanges in theshape of legs 16'at its ends which are secured to the base at theirlower ends, as with screws or the like. This material rest or tableincludes the supporting face 17 whereon the material which is to besliced rests and is .movable therealong, as indicated by the object ormaterial 18 in Fig. 1. An apron 19 continues from said supporting facedown to the base, extending from the near edge of the knife to the nearend of the machine.

' A gage plate 20 is mounted to have its operat- The form of thisinvention illustrated herein t guid during the Slicing Operationingsurface positioned substantially at right angles to the supporting face17, and is provided witha depending flange or apron 21 which bears uponapron l9 and is adjustably mounted thereon, as by the use ofsecuringelements 22, like 66 bolts, which extend through slots 23 inapron 19 and have threaded engagement in apron 21, to retain the apronstogether frictionally or with a yielding pressure. Index means orsetting means is provided, including theouterindexed knob 2i andactuating means, as forinstance a shaft 25 and gear pinion 26 thereonfor actuating arack 27 provided on apron 21 on the gage plate. 7

Ihe gage plate is with this construction arranged to be set for gagingor adjusting the thickness of slice, and is furthermore arranged sothat, by the additional turning of knob 24, said gage plate can be movedin the path of the cutting edge of the knife, substantially. asindicated in the full lines in Fig- 5 of the drawings, so that itfunctions a guard for the normallyexposed cutting portion of the knifeedge. This guarding feature of the gage plate, in addition to the usualknife guard 28 provided for the knife, as indicated in the drawings,thus furnishes a complete guard for all portions of the knife while themachine is at rest.

The guard 28 which extends on the greater part of the cutting edge ofthe knife is preferably made integral with a guide or guard plate 29which is seated within the depressed portion or cut-out portion 30provided in the knife, whereby the material is guided along the innerside of The material is engaged by the hands and moved along theadjacent faces on the material rest and on the gage plate, which arepositioned substantially perpendicular to each other and form thefeedway which is substantially V-shaped in cross-section, or istrough-shaped, preferably extending parallel to the base of the machine,and along which the material engaged by the hand is then readily movedduring the slicing operation; thus providing a simple and inexpensivemechanism and producing an economical machine on which the material isreadily sliced. These adjacent faces of the material rest and the gageplate, as well as the exposed face of the guide A scraper 31 ispreferably secured to the lower portion of the knife guard 28, to keepthe cutting edge of the knife clean from material, as best indicated inFig. 4. It has its scraping edge extending substantially vertically, tomore readily deflect downwardly or drop the particles of inaterialscraped from the knife.

The material rest or table has its lower portion fitting closely to theguide plate at the inward side of the knife, and also closely to theperipheral edge of the knife, so as to firmly support or hold up themeat or material in its proper position until it is completely sliced,and this arrangement thus avoids any frayed or ragged cutting of thematerial.

I claim:

1. In a slicing machine, a horizontal base and a knife mountedrotatablythereon, a material rest mounted inclined and stationary uponsaid base, a driving motor for said knife mounted on said base beneathsaid rest, a gage plate having its operating face positioned at aninclination with the co-operating face of the material rest, therebyproviding a trough-shaped feedway extending generally parallel to thebase and the knife edge and whereover the material is slid to and fro byhand, and means for adjusting the gage plate for the desired thicknessof slice and also for moving said plate in the plane of the knife edgetofunction as a complete and fully effective guard for thenormally-exposed portion of the cutting edge of the knife.

2. In a slicing machine, a horizontal base and a circular slicing knifemounted rotatably therei on, a material rest having flange means in theform of supporting legs depending from its upper part for mounting itstationary and at an inclination upon said base, said rest including anupper guide portion and a lower supporting porition, a gage plate havingan upper guide portion co-operating with the guide portion on said restfor providing a smooth trough-shaped feedway which has its lower edgesubstantially parallel to the base and to the knife edge and whereoverthe material is slid manually, means on the lower portion of said gageplate seated on said supporting portion on the rest, and means foradjusting the gage plate and its lower means along said supportingportion on the rest for regulating the thickness of slice and also formoving the gage plate in front of the normally-exposed cutting portionof the knife edge to function as an effective guard therefor.

3. In a slicing machine, a horizontal base and a rotary circular knifemounted thereon to have its cutting edge inclined thereto, a materialrest having flange means depending from its upper part to the base formounting the rest stationary and inclined thereon, said rest includingan upper guide portion and a lower supporting portion, a gage platehaving an upper guide portion extending substantially perpendicular tothe guide portion on said rest and therewith providing a smoothtrough-shaped stationary feedway which has its lower edge substantiallyparallel to the base and to t e knife edge and whereover the material ismoved manually to and fro of the knife, flange means on the lowerportion of the gage plate seated on the supporting portion of the rest,guard means including outer curved means for guardin the major portionof the knife edge also inner plate means integral therewith andpositioned within the confines of the knife edge to co-operate with thegage plate for guiding material along the knife, and means for adjustingsaid gage plate and its lower flange means upon said supporting portionfor regulating the thickness of slice and also to move the gage plate infront of the normally-exposed cutting portion of the knife edge andwithin the plane thereof to function as a guard and in conjunction withsaid curved guard means to protect the entire knife edge. 1
